You can use the terms "and" & "or" in your search; "or" phrases are resolved
first, then the "and" phrases. For example, searching for "black hole and
galaxy or universe" will find articles that have the phrase "black hole" in them
and also have either "galaxy" or "universe" in them. Please note that other
search syntax like quote marks, hyphens, etc. are not currently supported.

When you view web pages with matches to your search, the terms you searched for will be highlighted in yellow.

The FQXi podcast brings you the latest ideas in foundational physics and cosmology—and includes interviews with our members and other leading scientists.

ROBERT H MCEACHERN wrote on January 13, 2016Steve and Georgina,

Colors, like "red", cannot be measured at all; they are purely subjective responses to the objective properties of light. The best that we can do is measure properties like amplitudes and frequencies, and then deduce, rather than measure, that a normal human visual system, will produce the perception of the color, in response to those objective properties.

The difference is important. When you see the color yellow, on your computer screen, you are not "seeing"...

RE: "The Pound-Rebka experiment is compatible with Newton's emission theory of light", and "in general relativity, the speed of light falling towards the source of gravity idiotically DECREASES (in the gravitational field of the Earth the acceleration of falling photons is NEGATIVE, -2g)"

Have you actually read the paper? If you have not go to the second to the last paragraph and study the Plus and Minus signage before talking of compatibility or not with...
